Cisco Cisco E-Mail Manager Unity Integration Option Leaflet

In lab environments only, Unified CCMP software can be installed on the Unified ICM AW server. This 
co-resident model can be used only in labs due to the high processing requirements of the AW and a 
maximum configuration of 200 Named Agents.

Dedicated server mode supports two types of deployments:

Single server

In this simplex mode, all Unified CCMP components are installed on a single server. This is the 
recommended deployment for most Unified ICM customers because it represents the lowest cost of 
deployment and ongoing cost of ownership. This mode supports a maximum configuration of 1,500 
Concurrent Agents. For details on additional resource capacity criteria, refer to the Hardware and 
System Software Specification (Bill of Materials) for Cisco Unified ICM / Contact Center 
Enterprise & Hosted, Release 7.5(x), available at 

Dual server

In this mode, the front-end Unified CCMP components are installed on one server (the Web Server) 
and the back-end components are installed on another server (the Database Server). This allows the 
use of a firewall between the Web and Database Servers, which creates a DMZ for internet 
connectivity and provides for higher capacity and performance throughout the system. This mode 
supports a maximum configuration of 8,000 Concurrent Agents. For details on additional resource 
capacity criteria, refer to the Hardware and System Software Specification (Bill of Materials) for 
Cisco Unified ICM / Contact Center Enterprise & Hosted, Release 7.5(x), available at 

Both of the above deployments are non-resilient in nature. In the event of a Unified CCMP failure, revert 
to provisioning on Unified ICM or Unified CM until Unified CCMP is returned to service, at which time 
an automatic resynchronization occurs.

Either of the two standard deployment modes can be enhanced to a resilient configuration by using a 
duplicate set of hardware with Unified CCMP’s integrated data replication facilities to provide a 
geographically dispersed solution. Unified CCMP uses SQL Server replication to keep the two sides 
synchronized, similar to the Windows version of Unified CM. Cisco recommends these modes for 
customers who require fault tolerance. The system capacity limits remain unchanged from the equivalent 
standard deployments.

For details on required networking connectivity within geographically dispersed deployments, refer to 
the Hardware and System Software Specification (Bill of Materials) for Cisco Unified ICM / Contact 
Center Enterprise & Hosted, Release 7.5(x), available at

If a load balancing solution is to be provided to the front end (for example, Cisco Local/Remote 
Director), then it must support sticky connections.
